RHEL7 notes
Below are some helpful tips when working with RHEL7. They are not always recommended however sometimes helpful, especially when new to RHEL7…..
Disable dynamic network interface naming:
# vim /etc/default/grub
add the following to GRUB_CMDLINE_LINUX line
“biosdevname=0 net.ifnames=0”
# grub2-mkconfig –output=/boot/grub2/grub.cfg
reboot
Set Hostname:
# hostnamectl set-hostname “hostname”
Disable network manager and firewalld:
# systemctl stop NetworkManager
# systemctl disable NetworkManager
# systemctl stop firewalld
# systemctl disable firewalld
Register with subscription-manager:
# subscription-manager list –available
# subscription-manager attach –pool=
# subscription-manager repos –list
# subscription-manager repos –disable=*
# subscription-manager repos –enable <repo-name>
# subscription-manager repos –enable=rhel-7-server-rpms –enable=rhel-7-server-extras-rpms
